Wow! An uncredited James Horner score? Did he write original music or did they re-purpose Humanoids From The Deep music?
Nothing was recycled from Humanoid from the Deep it is an original score. But what he have composed was really short, as far as I know the album I have contains his complete score and this is only about 19 minutes long. I do not own any tracks of the additional music by Russell O'Malley but there's probably not more than 20 minutes in the film too.
